I watch him do it last month, and saw it again last night, so I confronted him and he just laughed and said, "you can't proove that." Then he walked away!!!!!!! How can I teach him a lesson in manners, he needs one!!!!!!!!!!

我上个月亲眼看到他这么干，昨晚又看到了，于是我对质他，他只是大笑说：“你没法证明。” 然后他就走开了！！！！！ 我该怎么让他懂点规矩呢？他太需要教育了！！！！！！！
